This is the first monitoring report for the Dye Branch Stream Restoration Project since the completion of Monitoring Year 5 (MY5) in 2015. A MY6 Post -Repair Monitoring Report was completed in February 2018 and documented the repairs and plantings that were completed in 2017. As a part of the repairs, two small areas were repaired on Upper Dye Branch and five small areas were repaired on Lower Dye Branch. The repairs consisted of repairing failed structures, installation of brush toe, streambank grading, installation of coir matting, riffle construction, and grading of the channel to reestablish the thalweg for proper flow through the new alignment. A supplemental planting was also performed to revegetate the areas that were graded during the repairs. A temporary seed mix and 420 bare root seedlings were planted in areas affected by the repairs to help revegetate. This report incorporates data that is associated with MY7 monitoring and includes a qualitative vegetation and stream assessment including vegetation monitoring of seven (7) annual monitoring plots, four (4) random/ temporary vegetation plots, morphological monitoring of ten (10) cross-sections, and hydrologic monitoring. This report also includes a visual assessment which incorporates multiple photo points, visual assessment of the vegetation, easement, and stream channel to document any problem areas that arise. These problem areas are documented in Tables 5 and 6 and depicted in Figure 2, the Current Condition Plan View. In addition to this MY7 monitoring, one additional year of monitoring will be conducted during 2019 with closeout activities conducted in 2020. Vegetation monitoring of the Dye Branch Stream Restoration Project includes annual monitoring of seven permanent vegetation plots, four temporary vegetation plots, and visual assessment of the easement as a whole. The site includes a diverse assemblage of 15 planted species of native trees and shrubs. Planted stems range from 4 to 22 per plot with 5 to 57 stems observed when volunteers are included. Based on the MY7 vegetation data, the average stem density for planted stems across all plots is approximately 382 stems per acre. This meets the year 7 success criteria of 210 planted stems per acre. When all planted and natural stems are combined, the average stem density is 1,012 stems per acre, and all seven plots meet the year seven success criteria. Four random vegetation plot transects were also performed to evaluate stems throughout the easement as a whole. The stem counts for the random vegetation transects were 9, 17, 12, and 32 which extrapolate out to 450, 850, 600, and 1600 stems per acre respectively. Dye Branch II 4 Equinox Project No. 92255 November 2018 MY7 Monitoring Report Regarding invasive -exotics, a contractor was hired to treat the invasive -exotic vegetation in November 2015. Since 2015 seven treatments have occurred at the Dye Branch site. Treatments occurred in June and September of 2018 (MY7) and have been effective. Treatments consisted of cut and stump sprays of a 50% glyphosate solution targeting Japanese honeysuckle (Lonicera japonica), kudzu (Pueraria montana), privet sp, Tree -of -Heaven (Ailanthus altissima), and multiflora rose (Rosa multiflora), mist blower treatments and foliar backpack sprays of a 2% clopyralid solution targeting kudzu and lespedeza (Lespedeza cuneate), basal bark in a 15% solution with diesel fuel targeting Callery pear (Pryus calleryana), Japanese honeysuckle, kudzu, mimosa (Albizia julibrissin), Privet sp., and multiflora rose, and foliar backpack spray of a 3% glyphosate solution targeting kudzu and privet sp. While treatments have been effective, populations of invasive -exotics, specifically kudzu, still persist throughout the easement, although in smaller quantities. Invasive -exotic treatments will continue until project closeout in 2020. Invasive -exotics will be monitored during future site visits. Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. Multiple areas of bank erosion were noted on all reaches (Figure 2, CCPV). All of these problem areas have existed since before the repair work was completed in late 2017. All of the implemented repairs completed in late 2017 are intact and performing as designed. Photos of all stream problem areas can be seen in the digital submission. MY7 morphologic monitoring of the Dye Branch Site included ten (10) cross-sections. Cross- sectional overlays are located in Appendix D and a summary of the data is located in Table 11 a and l lb. Cross-sections remained relatively stable between the Post -Construction data and the MY7 Monitoring efforts. Cross-section 5 showed the most substantial change, where a depositional bar formed along the left descending bank. Cross-sections 7 and 8 also slightly aggraded from Post -Repair to MY7. Riffle dimensions for the three different reaches also remained relatively stable during MY7. The most substantial dimensional changes for Cemetery Branch were a decrease in the bankfull width by 0.6 foot and lowering of the width/ depth ratio by 1.2. Dye Branch Upstream also saw a few dimensional changes, most notably the bankfull width decreased 1.7 feet and the width/ depth ratio increased by 1.6. Dye Branch Downstream showed an increase in bankfull width of 1.4 feet and the width/ depth ratio also increased by 1.4. A water level logger was installed in December of 2010 and has since recorded a total of 14 bankfull events. An equipment malfunction led to the loss of pressure transducer between MY5 (2015) and Post -Repair Monitoring (2018). A crest gauge was installed in February 2018 to monitor for evidence of bankfull events. Wrack lines well above the bankfull elevation were observed on Dye Branch Upstream, at Station 3+00, during a site visit on May 31St, 2018. While the crest gauge did not have a reading above bankfull during this visit, consistent wrack lines throughout the project area indicate a bankfull event occurred. Cross-referenced with gauge data from NCCRONOS, the suspected date was 4/24/2018. This was at least the fifteenth bankf ill event since the project completion. The crest gauge will be monitored in future site visits. Summary information/data related to the occurrence of items such as beaver or easement encroachment and statistics related to performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and Dye Branch II 5 Equinox Project No. 92255 November 2018 MY7 Monitoring Report supporting information formerly found in these reports can be found in the mitigation and restoration plan documents available on NCDMS' website. All raw data supporting tables and figures in the appendices are available from NCDMS upon request. 2.0 Methodology The stream monitoring methodologies utilized in Post -Repair Monitoring replicate those employed during the previous monitoring years and are based on standard guidance and procedures documents (Rosgen 1996; USACE 2003). Geomorphic measurements were taken during low flow conditions using a Nikon NPR 332 Total Station. Three-dimensional coordinates associated with cross-sections were collected in the field and geo-referenced (NAD83 North Carolina State Plane feet FIPS 3200). Geomorphic data included 10 cross-sections. Vegetation success is being monitored using 7 permanent monitoring plots and 4 random temporary transects. Vegetation monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008) and includes analysis of composition and density of planted species. Data is processed using the CVS data entry tool. In the field, the four corners of each plot were permanently marked with rebar and photos of each plot taken from the origin each monitoring year. 3.0 References Harrelson, Cheryl, C. Rawlins and J.
